Summary

the concept of spherical equivalent plays a pivotal role in simplifying the prescription and enhancing communication between eye care professionals and patients. The spherical equivalent is a calculated value that condenses the spherical and cylindrical components into a single power.

Conditions

  • Low Vision Aids

Interventions

DIAGNOSTIC_TEST

Contrast sensitivity

Contrast sensitivity will be assessed by using two different techniques of refraction on is Cylinderical lens and other is Spherical equivalent

OTHER

Refraction

Refraction will be performed and contrast sensitivity will be assessed to assess patient comfort level and compliance.
